Safety protective device used for numerical-control grinding machine

Abstract

The invention belongs to the technical field of safety protection of numerical-control grinding machines, and particularly relates to a safety protective device used for a numerical-control grinding machine. The safety protective device comprises a table rack, wherein the top of the table rack is fixedly equipped with a supporting frame; one side of the supporting frame is fixedly equipped with amotor; a grinding wheel is fixedly mounted on the output shaft of the motor; one side, close to the grinding wheel, of the supporting frame is fixedly equipped with two connecting rods; sides, close to each other, of the two connecting rods are fixedly equipped with the same protective cover; a through hole is formed in the inner wall of one side, close to the supporting frame, of the protective cover; the output shaft of the motor penetrates through the through hole and is rotatably connected to the inner wall of the through hole; the grinding wheel is positioned in the protective cover; first mounting holes are formed in inner walls of two sides of the protective cover; and first guide tubes are fixedly mounted in the two first mounting holes. The safety protective device can effectivelyavoid a condition that workpiece fragments transversely fly while the grinding machine works, guarantees safety of an operator, and also guarantees an operation environment to be clean.

Description

technical field [0001] The invention relates to the technical field of safety protection of numerical control grinding machines, in particular to a safety protection device for numerical control grinding machines. Background technique [0002] CNC grinding machine is a machine tool that uses abrasive tools to grind the surface of workpieces through numerical control technology. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones, abrasive belts, and free abrasives. Processing, such as honing machines, superfinishing machine tools, belt grinders, grinding machines and polishing machines, etc. CNC grinding machines include CNC surface grinders, CNC centerless grinders, CNC internal and external cylindrical grinders, CNC vertical universal grinders, CNC coordinate grinders, CNC forming grinders, etc. Grinding machines are grinding machines that use abrasive tools to grind the surface of workpieces. At present...

AI Technical Summary

Problems solved by technology

CNC grinding machines include CNC surface grinders, CNC centerless grinders, CNC internal and external cylindrical grinders, CNC vertical universal grinders, CNC coordinate grinders, CNC forming grinders, etc. Grinding machines are grinding machines that use abrasive tools to grind the surface of workpieces. At present, Most grinding machines use high-speed rotating grinding wheels for grinding. There will be a lot of debris when the workpiece is processed, and the debris will splash everywhere without protection, so a lot of spatter will be generated during the work process. staff causing injury

[0003] However, most of the existing grinding machines do not have protective devices, which cannot guarantee the safety of the grinding machine operators, and accidents such as iron filings and other splashes and injuries may occur during the processing
